Baculovirus transduction into mosquito C6/36 cells. (a) Schematic representation of a composite expression vector for generating recombinant baculovirus. The composite transfer vector contains the sv40 and pag1 promoters, which are designed to express mCherry in mammalian and insect cells, respectively. (b) Dose-dependent entry of baculovirus. C6/36 cells were transduced with different concentrations (MOI = 1, 10, and 100) of recombinant vABspmC baculovirus. (c) Gating of mCherry-positive cells by flow cytometry, shown the efficiency of baculovirus transduction using different MOIs. (d) Quantification of mCherry-positive cells to indicate transduction efficiency. (e) GP64-mediated entry of baculovirus. C6/36 cells were treated with a baculovirus-antibody mixture (neutralizing or non-neutralizing antibodies against GP64 protein). The mCherry fluorescence images were taken at 48 h post-transduction in both panel’s (b and e). Data represent the average ± SD (standard deviation) of three biological replicates (n = 3).
